There is a paperback book titled "Become The Arrow" by a fellow named Byron Ferguson. I may take some flak for suggesting this book, but he covers every aspect of shooting the "Bare Bow"
What I took from this book the most was coming to a solid anchor with the arrow directly under the eye - bow slightly canted, and a relaxed fluid release. Like Pat B said - if you find what works for you and repeat until it's ingrained in your muscles and mind, you'll be there.
